Embodiment
Corresponding to Fig. 1 and Fig. 2, an energy storage 1 according to the present invention has multiple battery cells 2, and these battery cells are directed in identical direction and in situation, have two parallel sides separately.In addition, each battery cell 2 has a monomer terminal 3(with a positive pole 4 and a negative pole 5 referring to Fig. 2 in situation separately).According to the present invention, these battery cells 2 are formed as so-called bag-shaped monomer now, between these bag-shaped monomers, arranging a thin slice 6 separately in situation, this thin slice comprises that multiple graphite granules 14, using as a cooling thin slice of using, that is to say the object for cooling these battery cells 2.Graphite has represented high pyroconductivity, makes like this thin slice 6 on large area, to be dissipated in the heat producing in the inside of this battery cell in the running of this battery cell 2 by these side surfaces of this battery cell 2.In addition, in the region of at least one monomer terminal 3, provide a cooling pipe 7, this cooling pipe is connected to corresponding monomer terminal 3 in heat conducting mode, and is connected to this thin slice 6 in heat conducting mode simultaneously.Energy storage 1 according to the present invention is numerous important because described design has advantages of.First, by thin slice 6, can realize cooling these independent battery cells on large area and still however still there is a structure space reducing, can improve thus the performance of energy accumulator 1, and can reduce the structure space demand of this energy accumulator.Because these cooling pipes 7 are conductively connected to corresponding monomer terminal 3 by direct heat, therefore not only can realize in addition on the large area of these sides battery cell 2 is carried out cooling but also can carry out effective cooling to monomer terminal 3, make like this to carry out cooling from inner side and outside simultaneously.By using bag-shaped monomer as battery cell 2, can exempt in addition up to now for encapsulating a housing of each battery cell, secondly first this housing need and make this energy accumulator 1 become heavy and expensive if it were not for unconsidered structure space.At this, bag-shaped monomer is just in time with conventional batteries monomer, namely have identical power by the battery cell of a packaging shell, but quite cheap.
At this, be formed a kind of plastic tab for the thin slice 6 of cooling these independent battery cells 2, wherein multiple graphite granules 14 are packed or be embedded in this plastic tab.Thin slice 6 be formed as a plastic tab make this thin slice can with one cheaply and flexibly mode produce, make like this, by corresponding injection molding instrument, can work to diversified size and/or change in size generally.In addition, thin slice 6 be preferably designed such that this thin slice large area that this thin slice not only covers adjacent battery cell 2 against respective side but also cover corresponding battery terminal 3.In this way, by thin slice 6, on the outside of this battery cell and in the region of the monomer terminal 3 of this battery cell, cool batteries monomer 2 is possible in large area simultaneously.
According to the structure of energy storage 1, at least two battery cells 2 that separated by a thin slice 6 each other can be arranged to be adjacent to each other, and form together a battery module 13 with a common monomer terminal 3.In the case, the self-evident ground of these independent battery cells 2 must electrically be connected each other.Then several these type of battery modules 13 can be arranged to be adjacent to each other in a kind of stacking mode in energy accumulator 1, wherein, between these battery modules 13, must arrange successively an extra thin slice 6 separately in situation.
These cooling pipes 7 preferably have outer cross section and a circular inner section of an angulation, wherein, outer cross section this angulation or rectangle allows in large area against corresponding monomer terminal 3, and circular interior cross section has the optimal design with regard to flowing.At this, consider Fig. 1, first can see flows enters pipeline 8 by one through the cooling agent of these cooling pipes 7 and flows into, and wherein these corresponding cooling pipes 7 are connected in their corresponding longitudinal end the outlet side that this enters the inlet side of pipeline 8 and is connected to a contrary discharge line 9.Therefore this cooling fluid flows through these cooling pipes 7 and does like this these independent monomer terminals 3 of cooling these corresponding battery cells 2 not only but also cooling these thin slices 6 also simultaneously corresponding to arrow 10, and these thin slices are connected in these independent battery cells 2 in heat conducting mode successively.Energy accumulator 1 according to the present invention is encapsulated by a housing 11 self-evidently, and this housing keeps together these independent battery cells 2.
Finally, consider the middle diagram of Fig. 2, can see that this thin slice 6 can have multiple protuberances 12 in large area due to its flexibility against corresponding battery cell 2 and in the region of monomer terminal 3, these protuberances are connected to these cooling pipes 7 in heat conducting mode.
In a word, can be for all motor vehicles according to energy accumulator 1 of the present invention, wherein especially highly advantageously this energy accumulator is used in motor vehicle driven by mixed power or motor vehicle, is namely used in the motor vehicles with high electric energy requirement.At this, energy storage 1 combines two cooling concepts independently up to now, is exactly to the cooling of monomer terminal 3 and cooling to the large area of these battery cells 2, can improve thus performance.Due to multiple bag-shaped monomers as these battery cells 2 and thin slice 6 this embodiment as cooling body, energy storage 1 according to the present invention also has compacter considerably structure compared with previous energy accumulator, has produced so sizable advantage with regard to weight and performance.
